Status of the read-out system of the Belle II pixel detector — •Andrei Rabusov, Igor Konorov, Dmytro Levit, Stefan Huber, and Stephan Paul — Technische Universität München

The new experiment Belle II at the SuperKEKB e⁺e⁻ collider at KEK, Tsukuba, Japan will start by late 2018 to continue searches of the New Physics in heavy flavor sector. In comparison to the previous detector Belle the new one is equipped with the pixel detector, which consist of 40 detector modules. The functionality of the pixel detector is studied during Phase II (period from November 2017 to May 2018) using only 4 modules installed inside the detector volume. In this report I present the current status of the Belle II pixel detector read-out system. The report will include the latest read-out scheme and results of Phase II commissioning with the corresponding laboratory tests. I will show in the first time the final version of the system architecture which achieves 20 Gb/s read-out speed test. Additionally, I will present the clustering algorithm based on moving window method, subevent building and the study of the effect on the average event size in case of overlapping triggers of two different data formats used in the read-out system: clustered and zero-suppressed data formats.
